Hamsters: Lazy or marathon-runners? Let your Raspberry Pi work that out
Last year, Los Angeles-based software engineer Michelle Leonhart brought two Roborovski hamster puppies into her home. Since then, she read on the internet that the average Roborovski hamster runs four marathons every night. She decided to put that to the test. Enter the Raspberry…
Create an internet speed analyzer with a Raspberry Pi
Vincent Willcox has taken one of Percheron Electronics’ e-paper HATs and created an internet speed analyser. He has released all the code onto GitHub so that you can re-produce his work. Take a look here. The speed scan is triggered either by…
Control ALL THE THINGS with the Raspberry Pi
Over at Makezine.com, Neil Davenport has used a Raspberry Pi, an Arduino and some other basic circuitry to build a speech interpreter that controls devices around the home. He uses the set-up with some off-the-shelf devices such as lights, and even a…
RasPiO GPIO Ruler for the Raspberry Pi goes on general sale
Alex Eames recently ran a successful Kickstarter for the RasPiO GPIO Ruler (pictured above). The ruler is a brilliant crib-sheet for people who want to use the GPIO pins of the Raspberry Pi but can never remember how to get started. When I…
Simple GPIO project using the Raspberry Pi and GPIO Zero
Giles Booth wanted to get started with physical computing using the Pi. Luckily, Ben Nuttall had just announced GPIO Zero, the new GPIO library from the Foundation. So, Giles got hold of some simple electronic components and wrote a traffic…
GPIO Zero test drive – throwing light onto the new library for the Raspberry Pi
Alex Eames from RasPi.TV has been putting GPIO Zero through it’s paces by creating an automatic security light which senses a) when it’s dark and b) when movement is detected and then triggers a light to come on. He’s used a…
CamJam EduKit 3 for the Raspberry Pi launches soon!
Big stuff happened yesterday and I haven’t got around to blogging it until now. Myself, Tim Richardson and Jamie Mann (from The Pi Hut) have been working for months (Months, I tell you! Months!) to create the new CamJam EduKit. This one…
GPIO Zero for the Raspberry Pi – more details
Alex Eames has scored a great interview with Ben Nuttall about his new GPIO library, GPIO Zero. Zero, which is written on top of Ben Croston’s great RPi.GPIO library, aims to abstract some of the more difficult or long-winded concepts and is…
Decryption machine reproduction with a Raspberry Pi (Turing-Welchman)
The Turing-Welchman Bombe was a decryption machine used in World War II to decipher Enigma-encoded German messages. There is a real one running at Bletchley Park: New Zealander Simon Jensen visited Bletchley and decided that he wanted to build a replica…
